To produce vthis enlargement. the inner faces of the top tand bottom walls ofl the head may be cut away at the point indicated, as will be un- -:der stood.

The bearing .4, above referred to, consists of mating or counterpart members a and 4* of true semi-annular shape, the lines of separation therebetween. being transverse to the axis of the rod. T he'ou'ter peripheral Walls of these members are formed With thickenedportions or treads'4, the edges of which terminate short of the adjacent edges of said Walls, thereby -producing front and rear shoulders 4d.

The remainder of the he'ad Iopening is ocupied by a pair of blocks 4 8 and 10,. of which the first-named is inthe vform' of a Wedge,its inclined.' working face co-a-cting With the correspondingly inclined or beveled outer side face of block 7.

not open to in3ury; moreover, they c an be turned oil' on alathe, require no shaping or- -ha'nd-fitting, and, consequently, .can be con?.
